Description

  The present invention relates to a hot water supply system, and more particularly, to a hot water supply system including a plurality of remote controllers.

  The remote controller of this type of hot water supply system has a power saving mode when the operation switch of the remote control is in the on mode. For example, the operation switch of the remote control is in the on state, and the water heater performs the combustion operation. In a state where there is no operation (in other words, combustion display data indicating that the combustion operation is being performed from the hot water supply device is not input to the remote control), and no operation state of the remote control continues for a certain time (for example, 10 minutes). When the predetermined condition (the entry condition to the power saving mode) is satisfied, the remote controller enters the power saving mode and power consumption in the remote control is suppressed (for example, see Patent Document 1).

  That is, under the power saving mode, the control unit of the remote control stops the display on the display unit (when the display unit is a fluorescent display tube, the fluorescent display tube is turned off and the display unit is a liquid crystal display panel). The predetermined power saving control is determined in advance so that power consumption by the remote controller is suppressed, such as turning off the backlight.

JP 2000-295680 A

  By the way, such a power saving mode is used when the switch operation is performed by the remote controller or when the hot water supply apparatus starts the combustion operation (in other words, when the combustion display data is input from the hot water supply apparatus). Since it is configured to be automatically canceled, there are the following problems.

  That is, depending on the mode of the hot water supply system, the hot water supply apparatus may start the combustion operation even when the user does not perform any remote control operation. However, in the conventional hot water supply system, there is no relation to such remote control operation. Even when a combustion operation is performed, combustion display data is transmitted from the hot water supply device to all remote controllers, so there is a problem that the power saving mode of each remote controller is canceled at the same time, and the power consumption of the remote controller increases. .

  Specifically, for example, if the hot water supply system is a hot water storage hot water supply system having a hot water storage tank that stores hot water used for hot water supply, bath filling, and heating functions, Combustion operation to keep warm water in the hot water storage tank even when none of the functions is used (that is, when the user does not operate the remote control at all or the hot water tap is not opened) May be performed. Similarly, in a hot water supply system equipped with an immediate hot water supply function in which hot water in a pipe is circulated and heated so that hot water at a set hot water temperature can be discharged immediately (with a small amount of discarded water) when the hot water tap is opened. In some cases, however, a combustion operation for the purpose of keeping warm water in the pipe is performed regardless of the user's remote control operation.

  On the other hand, for example, the remote control (bathroom remote controller) installed in the bathroom indicates that the above-described combustion operation is performed only for the purpose of keeping warm water in the hot water storage tank or piping when the user is absent from the bathroom. It is meaningless to display. In other words, depending on the purpose of combustion operation of the hot water supply device, there is a need for canceling the power saving mode (in other words, it is not necessary to display the state of the hot water supply device with the remote control). Canceling the power saving mode causes unnecessary power consumption. Similarly, it is not necessary to display combustion for the bathroom remote control when the floor heating device is operated alone or the kitchen remote control when only the bathroom heating dryer is operated alone, and wasteful power consumption is required. It was the cause.

  Furthermore, a switching power supply is preferably used as a display power supply for the display unit of the remote control. However, when the temperature inside the remote control becomes high due to the display on the remote control, the electrolytic capacitor used in the switching power supply is electrolyzed. There has been a problem that the remote control parts are deteriorated (therefore, the life of the remote control is shortened) such as the life of the electrolytic capacitor is shortened due to the evaporation of the liquid. Therefore, in order to extend the life of the remote controller, there has been a request to stop the display as much as possible when the display on the display unit is unnecessary.

  The present invention has been made in view of such problems and technical requirements, and an object of the present invention is to provide a hot water supply system that consumes less power in a remote controller and that causes less deterioration of remote control components. For the purpose.

  In order to achieve the above object, a hot water supply system according to claim 1 of the present invention discriminates the purpose of combustion operation in a hot water supply system in a hot water supply system having a remote controller having a control configuration for shifting to a power saving mode under a predetermined condition. When the combustion operation is started in the hot water supply device, the control unit of the hot water supply device sets a specific preset value according to the purpose of the combustion operation determined by the combustion purpose determination device. A control structure for canceling the power saving mode of the remote control is provided.

  That is, according to the hot water supply system of the first aspect, since the power saving mode of the specific remote controller set in advance according to the purpose of the combustion operation determined by the combustion purpose determining means is canceled, for each purpose of the combustion operation By setting in advance a remote controller that needs to display the state of the hot water supply device, it is possible to select only the remote controller that needs to be displayed in accordance with the purpose of the combustion operation and cancel the power saving mode. Therefore, according to the first aspect of the present invention, when there is a remote controller that does not need to cancel the power saving mode depending on the purpose of the combustion operation (that is, a remote controller that does not require the combustion display), such a display is unnecessary. Since the power saving mode can be set to be canceled only for the remote control except the remote control, the user can check the state of the hot water supply device with the remote control with the power saving mode canceled, while the other remote controls maintain the power saving mode. , Power consumption by the remote controller can be suppressed. Along with this, it is possible to prevent deterioration of components such as an electrolytic capacitor for a remote control in which the power saving mode is maintained.

  A hot water supply system according to claim 2 is the hot water supply system according to claim 1, wherein the hot water supply device includes a hot water heating terminal, and the combustion operation of the hot water supply device is intended for an independent operation of the hot water heating terminal. In the case where the power supply mode is not set, the hot water heating terminal main body or the remote control of the hot water heating terminal is caused to display a combustion display indicating that the hot water supply apparatus is in a combustion operation.

  That is, when the combustion operation of the hot water supply device is performed for the purpose of operating the bathroom heating dryer alone or the floor heating device alone, the corresponding hot water heating device body or its remote controller (the bathroom heating dryer operating alone) In case of remote control of bathroom heater / dryer, floor heater in case of stand-alone operation of floor heating device) is displayed only for combustion, and for remote control of other water heaters (for example, kitchen remote control and bathroom remote control) Maintain power saving mode. Therefore, the user can check the state of the hot water supply device with the hot water heating terminal main body in use or its remote controller, while the power consumption of other remote controllers can be suppressed. Moreover, deterioration of components such as an electrolytic capacitor can be prevented for a remote controller that maintains the power saving mode.

  The hot water supply system according to claim 3 of the present invention is the hot water supply system according to claim 1 or 2, wherein the power saving mode is canceled by the control unit of the hot water supply device with respect to the specific remote controller. It is performed by outputting a power saving mode release signal instructing release of the mode.

  That is, the hot water supply system according to claim 3 is configured such that a power saving mode release instruction (power saving mode release signal) is output from the controller of the hot water supply device to the remote controller that releases the power saving mode. It is possible to centrally perform the release control of the power saving mode of the remote controller according to the purpose of the combustion operation on the hot water supply apparatus side. In addition, as a power-saving mode cancellation | release signal here, for example, the new signal which requests | requires cancellation | release of power-saving mode can be set separately from the data (data which shows the state of a hot-water supply apparatus) displayed on a remote control, It is also possible to set the data itself to be displayed on the remote control to be used as the power saving mode release signal. That is, in the latter case, since the data to be displayed on the remote control is transmitted only to the remote control that cancels the power saving mode, the present invention is not accompanied by a change in the control configuration (software) on the remote control side. Can be applied.

  According to a fourth aspect of the present invention, there is provided the hot water supply system according to any one of the first to third aspects, wherein the remote controller for canceling the power saving mode indicates that the remote controller is performing a combustion operation. It is configured to display only the combustion display.

  That is, in the hot water supply system according to claim 4, only the combustion display indicating that the combustion operation is being performed is displayed on the remote controller that cancels the power saving mode. Therefore, even when the power saving mode is canceled, power consumption for the display can be minimized. In carrying out the invention according to claim 4, it is preferable to use a display device (for example, a light emitting diode or a fluorescent display tube) capable of displaying only the combustion display alone as the display unit of the remote controller.

  Moreover, the hot water supply system according to claim 5 is the hot water supply system according to any one of claims 1 to 4, wherein the controller of the hot water supply device is configured such that the purpose of the combustion operation is a predetermined purpose. When the combustion operation is completed, the power saving mode rush signal is output to instruct the remote controller that has released the power saving mode to return to the power saving mode.

  That is, in the hot water supply system according to claim 5, when the combustion operation is performed for a predetermined purpose set in advance, the power saving mode is saved with respect to the remote control that has been released from the power saving mode when the combustion operation is completed. A power saving mode entry signal is output to instruct the return to the mode. That is, the remote controller is returned to the power saving mode immediately after the end of the combustion operation, regardless of whether or not the entry condition to the power saving mode is satisfied. Therefore, according to the hot water supply system of claim 5, for example, when the combustion operation is performed only for the purpose of keeping the temperature of the hot water storage tank, the combustion operation is performed with respect to the specific remote controller that has released the power saving mode. A power saving mode rush signal is output upon completion, and the mode can be immediately shifted to the power saving mode, so that power consumption can be reduced.

  A hot water supply system according to claim 6 is the hot water supply system according to any one of claims 1 to 5, wherein the hot water supply device includes a bathroom heating dryer as a hot water heating terminal, and the control unit of the hot water supply device includes: Upon receiving a heating operation request from the bathroom heating dryer, information on whether the heating operation request is for the purpose of bathroom drying or bathroom heating is obtained through communication with the bathroom heating dryer. The combustion purpose determining means determines the purpose of the combustion operation based on the information.

  That is, in a hot water supply system provided with a bathroom heating dryer as a hot water heating terminal, a bathroom heating dryer is used for a heating operation request (that is, a request for hot water serving as a heat medium) made from the bathroom heating dryer to the hot water supply device. Since it does not include whether the operation is performed for bathroom drying or bathroom heating, in the hot water supply system according to claim 6, when a heating operation request is received from the bathroom heating dryer, the controller of the hot water supply device performs bathroom heating. The communication with the dryer is configured to obtain information about whether the heating operation request is made for the purpose of drying the bathroom or for the purpose of heating the bathroom from the bathroom heating dryer. This makes it possible for the combustion purpose determination means to grasp in detail the purpose of the heating operation request (that is, the combustion operation), and to perform the power saving mode release control and rush control more finely.

  A hot water supply system according to a seventh aspect is the hot water supply system according to any one of the first to sixth aspects, wherein an input operation for performing a function of the remote control is performed in a state where the remote control is in a power saving mode. In this case, when the function is a function that does not involve the combustion operation of the hot water supply device, a control configuration is provided in which the function is returned to the power saving mode when the function ends.

  That is, in the hot water supply system according to claim 7, a function that does not involve the combustion operation of the hot water supply device in the state where the remote control is in the power saving mode (specifically, intercom call function, clock time adjustment function, bath operation, etc.) At least one of the operation reservation function, hot water temperature / bath temperature setting function, and maintenance monitor display function), the remote control is turned on when the function is completed. Return to power saving mode. Therefore, in the hot water supply system according to the seventh aspect, the power consumption mode is restored immediately after the end of the function, so that power consumption by the remote controller can be suppressed.

  According to the present invention, when the hot water supply apparatus performs the combustion operation, the power saving mode of all the remote controllers is not canceled uniformly, but only for a specific remote controller set in advance according to the purpose of the combustion operation. Since the power mode is canceled, the power saving mode can be maintained for the remote controller that does not need to display the state of the hot water supply device, and an increase in power consumed by the remote controller can be prevented. Further, with respect to the remote controller in which the power saving mode is maintained, it is possible to suppress the deterioration of components by stopping the display on the display unit of the remote controller.

  Further, in the present invention, when the hot water supply apparatus includes a hot water heating terminal and the combustion operation of the hot water supply apparatus is intended for single operation of the hot water heating terminal, instead of canceling the power saving mode of a specific remote controller, By configuring the hot water heating terminal body or the remote control of the hot water heating terminal to display a combustion display indicating that the hot water supply device is in a combustion operation, it is possible to maintain the power saving mode for the remote control of other hot water supply devices. It is possible to prevent the power consumed by the remote controller from increasing. Further, with respect to the remote controller in which the power saving mode is maintained, it is possible to suppress the deterioration of components by stopping the display on the display unit of the remote controller.

  In addition, the present invention is configured such that the power saving mode is canceled by the power saving mode cancellation signal output from the control unit of the hot water supply device, thereby canceling the power saving mode of each remote control. This can be done centrally on the device side. In particular, the present invention can be applied without changing the control configuration of an existing remote controller by using the data itself displayed on the remote controller as the power saving mode release signal.

  Furthermore, the present invention is configured such that the remote controller in which the power saving mode is canceled displays only the combustion display of the hot water supply device, thereby reducing the power consumption when the power saving mode is canceled as much as possible. be able to. In particular, by using a display device that can display only the combustion display alone as the display unit, the effect of suppressing the power consumption can be enhanced.

  Further, according to the present invention, when the preset predetermined combustion operation is completed, the controller of the hot water supply device outputs a power saving mode entry signal to the remote controller that has released the power saving mode. With this configuration, the remote controller can be returned to the power saving mode immediately after the end of the combustion operation, and the power consumption can be reduced.

  Further, according to the present invention, when there is a heating operation request from the bathroom heater / dryer to the control unit of the hot water supply apparatus, the control unit displays information on the purpose of the heating operation request (bathroom drying purpose / bathroom heating purpose) in the bathroom. By being configured to acquire from the heating dryer, the purpose of the combustion operation by the combustion purpose determination means can be determined in more detail. As a result, it is possible to select in detail the remote controller that cancels the power saving mode and the remote controller that enters the power saving mode, and it is possible to further reliably reduce the power consumption.

  Further, the present invention is a function in which, when an input operation for performing a function in the remote control is performed in a state where the remote control is in the power saving mode, the function in which the operation is performed does not accompany the combustion operation of the water heater. In some cases, by configuring the remote control to return to the power saving mode when the function ends, the remote control can be returned to the power saving mode immediately after the end of the function that does not involve combustion operation. Power consumption can be suppressed.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a system configuration diagram showing an example of a schematic configuration of a hot water supply system according to the present invention. The hot-water supply system shown in FIG. 1 is a hot-water heating / heating system in which a hot-water supply device 1 serving as a heat source device has a hot-water heating function in addition to a hot-water supply / bath-water filling function. A dryer 2 and a floor heating device 3 are provided, and a plurality of remote controllers 4 to 7 are provided as operation remote controllers for these functions.

  Specifically, 4 is a kitchen remote control installed in the kitchen for hot water and hot water filling functions, 5 is a bathroom remote control installed in the bathroom for hot water and hot water filling functions, 6 is a remote control for bathroom heating dryers, and 7 is a floor. 2 shows a remote control of a heating device.

  In addition, since the basic structure of such a hot-water supply / heating system is well-known, the detailed description about this basic structure is abbreviate | omitted, and demonstrates below centering on the part relevant to this invention.

  As described above, the hot water supply apparatus 1 is a hot water supply / heating heat source machine having functions of hot water supply, bath filling, and heating, and includes a control unit 1a as control means for each part of the hot water supply apparatus. The control unit 1a includes a microcomputer as a control center, and is connected to a hot water heating terminal, a remote controller, and the like via communication means (not shown).

  Specifically, a kitchen remote controller 4 and a bathroom remote controller 5 are connected to the control unit 1a via a two-core communication line 8, and a bathroom heating is provided via a communication line 9 for three-wire bidirectional communication. The controller 2a of the dryer and the remote controller 7 of the floor heating device are connected.

  More specifically, the kitchen remote controller 4 and the bathroom remote controller 5 are configured to perform power superimposition communication with the control unit 1a of the hot water supply device 1 via the two-core communication line 8, and supply power from the hot water supply device 1. It is comprised so that it may communicate with the control part 1a, receiving. That is, when an operation switch, a temperature control switch for hot water supply set temperature, or the like is operated by the kitchen remote controller 4 or the bathroom remote controller 5, a control signal corresponding to the operation is transmitted to the control unit 1a of the hot water supply apparatus 1 and the hot water supply apparatus 1 The control part 1a is configured to receive data indicating the state of the hot water supply device (for example, combustion display data indicating that the combustion operation is being performed).

  On the other hand, the bathroom heater / dryer 2 is a hot water heating terminal capable of two modes of operation, namely, a bathroom heating operation and a bathroom drying operation (an operation in which bathroom heating and ventilation are performed at the same time). I have. And this control part 2a and the control part 1a of the hot-water supply apparatus 1 are communicatively connected by the communication line 9 for two-way communication. Here, the controller 2a of the bathroom heater / dryer 2 includes a microcomputer as a control center, and a remote controller 6 for the bathroom heater / dryer is further connected to the controller 2a.

  The remote controller 6 of this bathroom heating / drying machine is a remote control provided on the wall of a dressing room adjacent to the bathroom, etc., and makes the bathroom heating / drying machine 2 perform a bathroom heating operation or a bathroom drying operation. It is configured to allow operations such as setting the heating temperature. For example, when the bathroom drying operation is selected and operated in the remote controller 6 of the bathroom heating / drying machine, the fact is given to the control unit 2a of the bathroom heating / drying machine 2, and the control unit of the hot water supply apparatus 1 is transmitted from the control unit 2a. A control signal (heating operation request) for requesting heating operation is transmitted to 1a, and the controller 1a of the hot water supply device 1 supplies predetermined hot water to the bathroom heating dryer 2 in response to the heating operation request. It is configured to perform control. The remote controller 6 of the bathroom heater / dryer is configured to acquire data on the state of the hot water supply device 1 via the control unit 2a of the bathroom heater / dryer 2 and display the state of the hot water supply device 1 on the display unit. Has been.

  On the other hand, in the floor heating device 3, the remote controller 7 of the floor heating device is communicatively connected to the control unit 1 a of the hot water supply device 1. The remote controller 7 of the floor heating apparatus is a remote controller provided on a wall surface such as a living room where the floor heating panel 3a is arranged. When there are a plurality of floor heating panels 3a, which panel is used for heating and setting of the heating temperature It is comprised so that operation of these etc. can be performed. For example, when an operation for starting the heating operation is performed with the remote controller 7 of the floor heating device, a heating operation request is transmitted to the control unit 1a of the hot water supply device 1, and the control of the hot water supply device 1 is performed according to the heating operation request. The unit is configured to execute control for supplying hot water to the floor heating panel 3a, such as opening a thermal valve (not shown) communicating with the floor heating panel 3a. In addition, the remote controller 7 of this floor heating apparatus acquires the data regarding the state of the hot water supply apparatus 1 directly from the control part 1a of the hot water supply apparatus 1 via the communication line 9, and displays the state of the hot water supply apparatus 1 on the display unit. It is configured. In the present embodiment, the remote controller 7 and the controller 1a of the hot water supply apparatus are shown in a communication connection through two-way communication. It is also possible to do.

  Note that the microcomputer of the control unit 1a is provided with storage means (memory) (not shown), and data necessary for power saving mode release control for each of the remote controllers 4 to 7 to be described later is stored in this storage means. (Details will be described later).

  FIG. 2 is a block diagram showing a schematic configuration of each of the remote controllers 4 to 7 in such a hot water supply system. As shown in FIG. 2, each of the remote controllers 4 to 7 includes an operation unit 11 having various operation switches, a display unit 12 having a display device such as a fluorescent display tube and a liquid crystal display panel, and an operation unit 11. The main part includes a control unit 13 that controls each part of the remote controller such as reception of an operation signal and display control of the display unit 12, and a communication interface 14 that performs power supply superposition communication and bidirectional communication.

  Of these remote controllers 4 to 7, the kitchen remote controller 4 and the bathroom remote controller 5 have the control unit 13 provided with a power saving mode. The remote controller 4 or 5 has a preset condition (to enter the power saving mode). The control unit 13 of each of the remote controllers 4 and 5 is configured to execute predetermined power saving control. This predetermined condition can be set as appropriate. For example, when the hot water supply apparatus 1 does not perform the combustion operation (in other words, the combustion display data is not input from the hot water supply apparatus 1 to the remote control), The condition is that it has continued for a certain time (for example, 10 minutes). And the control part 13 of each said remote control 4 and 5 each determines whether this condition is satisfy | filled, and when it determines with satisfy | filling this condition, each control part 12 enters into a power saving mode independently. Is set to

  And as power saving control performed in such a power saving mode, for example, the control unit 13 of each remote controller stops the display of the display unit 12 (the display unit 12 is a fluorescent display tube, a light emitting diode or the like). The display device is turned off when the display device performs light emission display, and the backlight is turned off when the display unit 12 does not emit light as in the case of the liquid crystal display panel. For example, predetermined predetermined control is executed so that power consumption by the remote controller is reduced.

  When the operation unit 11 is operated or the data indicating the predetermined state of the hot water supply device 1 is received in the state of entering the power saving mode, the control unit 13 of the remote controller sets the power saving mode. It cancels and it returns to a normal state (namely, power-saving control is stopped and the display of the display part 12, etc. are returned to a normal state).

  In the hot water supply system having the remote controls 4 and 5 having such a power saving mode, the present invention controls the release of the power saving mode as described below by the control unit 1a of the hot water supply apparatus 1 for each of the remote controls 4 to 7. And so on. FIG. 3 is a flowchart illustrating an example of the power saving mode release control.

  That is, in the present invention, the control unit 1a of the hot water supply apparatus 1 is provided with the combustion purpose determining means 1b for determining the purpose of the combustion operation of the hot water supply apparatus 1. When the hot water supply apparatus 1 starts the combustion operation, the control of the hot water supply apparatus 1 is performed. The unit 1a is configured to cancel a preset power-saving mode of a specific remote controller according to the purpose of the combustion operation determined by the combustion purpose determination means 1b.

  Specifically, the combustion purpose determining means 1b is a means functionally realized by a microcomputer program of the control unit 1a, and details of the control being executed in the control unit 1a, each of the remote controls 4-7, etc. The purpose of the combustion operation is determined through communication with.

  For example, when the hot water supply apparatus 1 performs the combustion operation based on the operation of the kitchen remote controller 4 or the bathroom remote controller 5, the combustion operation is performed with an operation related to the hot water supply function (for example, an operation switch) by communication with the kitchen remote controller 4 or the bathroom remote controller The flow rate is equal to or higher than the minimum operating flow rate after the on-operation of) or the operation related to the bath filling function (operation of the bath filling switch). That is, the purpose of the combustion operation is determined based on the control signal given from the kitchen remote controller 4 or the bathroom remote controller 5.

  Further, when the combustion operation is performed based on the heating request from the bathroom heating dryer 2, the control unit 1a that has received the heating operation request communicates with the control unit 2a of the bathroom heating dryer 2 through the heating operation. Information on whether the request is based on the bathroom drying operation (for bathroom drying purpose) or the bathroom heating operation (for bathroom heating purpose) is acquired from the control unit 2a, and based on this information, the combustion operation is performed. Determine the purpose. That is, the controller 2a of the bathroom heater / dryer 2 recognizes whether the switch operation of the bathroom drying operation or the bathroom heating operation is performed by the remote controller 6 of the bathroom heater / dryer. The information is acquired and the combustion purpose is determined by the combustion purpose determination means 1b.

  Moreover, when performing combustion operation based on the heating request | requirement from the remote control 7 of a floor heating apparatus, it determines with combustion operation being floor heating by communication with the said remote control 7.

  Further, the combustion purpose determining means 1b determines the combustion purpose of the hot water supply apparatus 1 also based on the contents of the control being executed in the control unit 1a. For example, when the hot-water supply system is a hot-water storage system, even if all the functions of hot-water supply, bath filling, and heating are not used (that is, when the user does not perform any remote control operation) Although a combustion operation may be performed to keep warm water in the hot water storage tank, the combustion operation performed only for the purpose of maintaining the temperature of the hot water storage tank is executed by the control of the control unit 1a of the hot water supply device 1 itself. In such a case, it is determined that the combustion operation is intended to keep the hot water storage tank warm. Similarly, in a hot water supply system having an immediate hot water function, it is performed for the purpose of keeping warm water in the piping performed independently of the user's remote control operation (however, the quick hot water function is requested in advance by the remote control operation). As for the combustion operation, such a combustion operation is executed by the control of the control unit 1a itself of the hot water supply apparatus 1, and in this case, it is determined that the combustion operation is for the purpose of keeping heat in the pipe.

  As described above, the control unit 1a of the hot water supply device 1 first determines whether or not the hot water supply device 1 has started the combustion operation (see step S1 in FIG. 3), and when the hot water supply device 1 starts the combustion operation, The purpose of the combustion operation is determined based on the contents of the control being executed in the control unit 1a and communication with each of the remote controllers 4 to 7 (see step S2 in FIG. 3).

  When the purpose of the combustion operation is determined, the control unit 1a then cancels the preset power saving mode of the specific remote controller according to the purpose of the combustion operation.

  Specifically, data that associates the purpose of the combustion operation with the remote controller that cancels the power saving mode is stored in advance in the storage unit of the microcomputer of the control unit 1a, and the control unit 1a is based on this data. A remote controller for canceling the power saving mode is specified, and a power saving mode cancel signal for instructing the remote controller to cancel the power saving mode is output (see step S3 in FIG. 3).

  Here, the purpose of the combustion operation and how the remote control for canceling the power saving mode can be set as appropriate, but this setting depends on the relationship between the purpose of the combustion operation and the location where the remote control is installed. Is set. For example, there is no remote control operation by the user, such as the combustion operation performed only for the purpose of keeping warm water in the hot water storage tank described above, or the combustion operation performed only for the purpose of keeping warm water in the piping in the quick hot water function. In the case of the combustion operation that is also performed, it is set so that the power saving mode of the remote controller (for example, the kitchen remote controller 4) that is relatively easily noticeable by the user is canceled.

  Here, as the power saving mode release signal output from the control unit 1a of the hot water supply device 1, a new request for releasing the power saving mode is provided separately from the data (data indicating the state of the hot water supply device) displayed on the remote controller. Although it is possible to set a signal and instruct the remote controller to cancel the power saving mode, in this embodiment, the data itself displayed on the remote control (specifically, the combustion display data) is used as the power saving mode cancellation signal. . That is, the control unit 1a is configured such that data to be displayed on the remote control is transmitted only to the remote control that cancels the power saving mode. Thus, the present invention can be applied without changing the control configuration (software) on the remote control side.

  In addition, when the combustion operation is terminated in a state where the power saving mode is released for a specific remote controller according to the purpose of the combustion operation in this way, the remote controller that has been released from the power saving mode is not connected to the power saving mode thereafter. When a predetermined condition for shifting to the mode is satisfied, the power saving mode is entered.

  As described above, according to the present invention, by setting in advance a remote controller that needs to display the state of the hot water supply device 1 according to the purpose of the combustion operation, only the remote controller that needs to be displayed is selected and the power saving mode is set. It can be canceled and power consumption can be suppressed in other remote controllers that do not require display. Along with this, it is possible to prevent deterioration of components such as an electrolytic capacitor for a remote control in which the power saving mode is maintained.

  Here, when the purpose of the combustion operation is for a single operation of the hot water heating terminal (bathroom heating dryer 2 or floor heating device 3), these remote controls 6 and 7 are provided with a power saving mode. In this case, instead of canceling the power saving mode of the remote controller, the hot water heating terminal main body or the remote controllers 6 and 7 of the hot water heating terminal are made to display a combustion display indicating that the hot water supply apparatus is in the combustion operation. Configured.

  That is, for example, when the purpose of the combustion operation of the water heater is the single operation of the bathroom heater / dryer 2, a display unit (not shown) provided on the body of the bathroom heater / dryer 2 (for example, a light-emitting display by a light emitting diode or the like) Or the remote controller 6 of the bathroom heater / dryer 2 is configured to display the combustion, and the remote controllers (kitchen remote controller 4 and bathroom remote controller 5) of the other hot water supply devices are configured to maintain the power saving mode. Therefore, in this case, the user can check the state of the hot water supply device with the hot water heating terminal main body or its remote controller for the hot water heating function in use, and can suppress power consumption for the other remote controllers.

Embodiment 2
Next, a second embodiment of the present invention will be described. In the second embodiment, in addition to the above-described control for canceling the power saving mode by the hot water supply device 1, the entry control to the power saving mode is performed by the control unit 1 a of the hot water supply device 1. Therefore, except for the change in the control configuration of the control unit 1a, the other points are the same as those in the first embodiment, and therefore, the same reference numerals are given to the parts having the same configuration, and the description is omitted.

  In this embodiment, when the purpose of the combustion operation determined by the combustion purpose determination means 1b is a predetermined purpose set in advance, when the combustion operation ends, the control unit 1a of the hot water supply device 1 saves power. It is configured to output a power saving mode entry signal that instructs the remote control that has been released from the mode to return to the power saving mode.

  That is, for example, when a bathroom drying operation is performed in the bathroom heating dryer 2, the embodiment described above describes a case where the power saving mode of the kitchen remote controller 4 is canceled according to the purpose of the combustion operation of the hot water supply device 1. However, it is usually impossible to use hot water in the kitchen immediately after the end of the bathroom drying operation. That is, in this case, there is no problem even if the kitchen remote controller 4 is immediately returned to the power saving mode. Even if hot water is used immediately in the kitchen, the hot water tap is opened, water flow exceeding the minimum operating flow rate occurs, and combustion operation is started. The mode is released.

  Therefore, in the present embodiment, for the combustion operation that may be immediately returned to the power saving mode in this manner, the purpose of the combustion operation is separately stored in advance in the storage means, and when the combustion operation is completed, The control unit 1a determines whether or not the completed combustion operation matches the purpose stored in the storage means, and if it matches, the remote controller that has released the power saving mode enters the power saving mode. It is configured to output a power saving mode entry signal instructing a return.

  In this case, when the remote controllers 4 and 5 receive the power saving mode entry signal from the control unit 1a of the hot water supply device 1, whether or not the entry conditions for the preset power saving mode are satisfied are satisfied. Instead, it is configured to immediately return to the power saving mode.

  As described above, according to the present embodiment, when the combustion operation is finished, the remote controller that has been released from the power saving mode quickly returns to the power saving mode. Can be achieved.

  In this embodiment, the purpose of the combustion operation and how the remote controller to return to the power saving mode can be set as appropriate, and the setting depends on the relationship between the purpose of the combustion operation and the location of the remote controller. Set accordingly.

Embodiment 3
Next, a third embodiment of the present invention will be described. In the third embodiment, in addition to the power saving mode release control and the power entry mode entry control by the hot water supply apparatus 1 according to the first embodiment or the second embodiment described above, the power saving mode is set to another condition. Inrush control is added. Accordingly, except for the change in the control configuration of the control unit 1a, the other points are the same as those in the first and second embodiments.

  In the present embodiment, when each of the remote controllers 4 and 5 is in a power saving mode and an input operation is performed to perform a function of the remote controller, the function is burned by the hot water supply device 1. In the case of a function that does not involve operation, it is configured to return to the power saving mode when the function ends.

  That is, the input operation (remote control operation) on the remote controller includes many operations that do not involve the combustion operation of the hot water supply device 1 such as operations related to the intercom call function and operations for displaying a monitor for system maintenance. Even in such an operation that does not involve the combustion operation of the hot water supply device 1, the power-saving mode of the remote controller is canceled by the operation of the operation unit 11. Therefore, in this embodiment, the operation is immediately saved after the operation is completed. It is configured to return to the power mode.

  Specifically, among the operations that do not involve the combustion operation of the hot water supply device 1, an operation for returning to the power saving mode immediately after the operation is finished (specifically, an interphone call function, a clock time adjustment function, a bath operation, etc.) Storage means (not shown) provided in advance in the control unit 13 of each remote controller 4, 5, at least one of the operation reservation function, hot water supply temperature and bath temperature setting function, and maintenance monitor display function. Or in the storage means of the control unit 1a of the hot water supply device 1, and the control unit 13 of each remote controller 4 or 5 or the control unit 1a of the hot water supply device 1 determines whether or not the operation has been completed. When it is determined that has been completed, the apparatus is configured to immediately return to the power saving mode. When each remote controller 4, 5 determines whether to return to the power saving mode, the entry condition to the power saving mode in each remote controller 4, 5 is changed, and the controller 1 of the hot water supply device 1 makes the determination. In the case of the configuration, the power saving mode rush signal is also output from the control unit 1a in this case.

  As described above, in this embodiment, when the remote control operation that does not involve the combustion operation of the hot water supply device 1 ends, the remote control immediately returns to the power saving mode, so that power consumption by the remote control is suppressed and component deterioration is prevented. be able to.

  Note that the above-described embodiments merely show preferred embodiments of the present invention, and the present invention is not limited to these, and various design changes can be made within the scope thereof.

  For example, in the above-described embodiment, the configuration in which the power saving mode of a specific remote controller is canceled according to the purpose of the combustion operation of the hot water supply device 1, that is, the case where the remote controller is returned to a normal state has been described. When canceling the power saving mode, it is possible to display only the combustion display indicating that the combustion operation is being performed on the display unit 12 of the remote control instead of returning the entire remote control to the normal state. is there. In this case, as the display unit 12 of the remote controller, it is preferable to use a display device (for example, a light emitting diode or a fluorescent display tube) that can display only the combustion display alone.

  Further, in the above-described embodiment, there is a case where data for associating the purpose of the combustion operation with the remote controller that cancels the power saving mode (or the remote controller that returns to the power saving mode) is stored in the storage unit of the control unit 1a in advance. Although shown, this data can be configured so that the user can arbitrarily change the setting by a predetermined operation of the remote controller.

  In the above-described embodiment, the present invention is applied to a hot water supply system having functions of hot water supply, bath filling, and heating, but the present invention is a hot water supply system provided with a plurality of remote controllers. Of course, the present invention can also be applied to a hot water supply system having a single function of hot water supply and a hot water supply / bath water bath function.

  Furthermore, in the above-described embodiment, the case where the remote controller included in the hot water supply device 1 includes the kitchen remote controller 4 and the bathroom remote controller 5 with respect to the hot water supply / bath hot water filling function has been described. It is also possible to provide a sub-remote controller, and in the above-described embodiment, the remote controller 6 for the bathroom dryer and the remote controller 7 for the floor heating apparatus have not been provided with the power saving mode.
